IEDGE-BURNISHING MACHINE.

SPECIFICATION forining part of Letters Patent No. 364,156, dated May 31, 1887.

I 7 Application filed November 8, 1886. Serial No. 218,3!9. (N0 model.)

To all whom it may concern.-

Be itknown that I, ROBERT AsHE, of Somerville, in the county of Middlesex and State of Massachusetts, have'invented a new and useful Improvement in Edge-Burnishing Machines, of which the following, taken in connection with the accompanying drawings, is a specification. A

My invention relates to that class of edgeburnishing machines in which theboot or shoe to be operated upon is held and guided by the hands of the operator,the object being to so improve the construction of the operative parts that the jar or vibration usuallyresulting from the high rate of speed at which this class of machines are driven, and the consequent danger to the health of those who op-- base being omitted as not needed in this case.

Fig. 2 is a perspective view showing the burnishing-irons and their more immediate connecting parts. Fig. 3 is a vertical section showing details. Fig. 4 is a front elevation of my machine. Fig. 5 is a vertical section enlarged, showingin detail the parts connected to the burnishing-irons and their adjuncts; and t Fig. 6 is a vertical section showing a method of connecting to one of the rocking shafts a circular burnishing-iron.

A, Figs. 1 and 4, shows the main post or standard, to which I attach my working machine.

. A A A A A A 0 0 Fig. l, constitute the frame of the machine.

'0, Fig. 1, represents the main shaft of the machine. To this shaft 0, I attach the driving-pulley C and balance-wheel 0*. Tothe end of the shaft 0, by means of crank wristpins, I unite two working-links, H and C, Fig. 4. These two working-links H and G serve to operate the two burnishing-irons H and D.

The burnishing-iron D is operated as 'follows: The link 0, Fig. 4, is moved backfand wrist-pin on the main shaft 0 is communicatedto the working-shaft D. The rear end' of the shaft D is held in place by the part 'A of the frame, which it enters, as shown in Fig. 5, and the body of the shaft is held centrally by the hollow shaft H Figs. 5 and 6, through which it extends.

To the front end of the shaft D, I attach at D a block, D Figs. 2, 3, 4, and 5. This block swings back and forth with the rocking of the shaft D, and has aprojection or arm, D Figs. 2, 3, and 5, to which I attach, by means of a pivot, D the journal-piece D, Fig. 2, the said journal-piece D having extending downward from it the tool-holder D D being the burnishing tool or iron, which is held in place by a set-screw, D", or other suitable means, Fig. 2. The arm D is formed with a clamp, as indicated at d, Fig.2, for the purpose of holdingthejournal-pin D Fig. 3. Thejourother holder, H, as indicated by dotted lines in Fig. 5. To secure the holder D and iron D in their desired positions, I have the following device:

An upwardly-projecting segment-arm, E, is attached to the journal-piece D, Figs. 2 and 3. This segment-arm has a notch, E and a projection, ET, which engage, as may be required, with the lever E", the lever E being pivoted to the block D by the pivot E", Figs.

2, 3, and 4, and held down by the spring E When the iron or tool D is in use,the lever E rests in the notch FF and holds the tool D out ICQ ready for use, as shown in Fig. 1; but when the tool D" is not to be used the lever E is raised out of the notch E, and the tool D and its holder D are turned inward, (swinging on 5 the journal-pin D,) so that the lever E rests against the projection E and holdstheholder and tool in the position indicated by the dotted lines in Fig. 5.

I will now describe my method ofoperating 10 the second burnishing iron or to0l,H. On the main driving-shaft C, Fig. 1, I have a crank wrist-pin which operates the link H, Fig. 4, and the link in turn, acting through the pin H and lever H, which are connected to the [5 hollow shaft H by the hub H, Figs. 4 and 5,

causing the hollow rocking shaft H to oscillate and to give a vibrating motion to the arm H, tool-holder H and bu rnishing tool or iron H". The burnishing tool or iron H is held in place by the set-screw H or other suitable means.

In Fig. 6 I have shown a modified form of one of my burnishing tools or irons. To use the modified-that is, the circular-iron K", I

remove the rocking shaft D of Fig. 5, and insert in its place the rocking shaft K, Fig. 6. To the end of the shaft K", I firmly attach the boss K. This .boss K has screwed to it a snaplateh, K, the end of which engages with hub K ofthe circular burnishing iron K and holds it in place. K is aprojection on the shaft K, which enters into a socket made in the hub K and forces the circular iron K to vibrate with the shaft K. The bed K of the burnish- 5 mg tool or iron K is inclined, as shown, so that the operator may be enabled to press the shoe or boot edge against it and not require any other rest for hand or fingers.

By arranging the rocking shafts H and D 4c and the clamping-hubs H and G" as I have shown in Fig. 5, I am enabled to adjust the said hubs to compensate for the wear of the connectingand operating parts.

B", Fig. 1, is a table which serves for a rest for the hands of the operator when such rest is needed. The table is supported by the following-described means: A Figs. 1 and 4, is .a projection extending from the standard A. Extending from A ,I have a large-headed bolt, B, the shank of which is held in place by the set-screw B. Through the head of the bolt B a horizontal bar, B, slides, said bar being held by a set-screw, B". At the end of the bar B, I attach a hub, B, and vertically in it is placed an adjustable rod, B held by the set-screw B Fig. 4. To the lower end of therod B, I attach an arm B", Fig. 1, which supports the table B by screws 13 13? and bosses B B".

To prevent the table 13 fromswingi ng around too far, I place a stud, b, on the arm B and a pin, b, in the rod B. This device will allow the table to swing to the right against the standard A and out of the way oftlic operator, but will limit its motion to the left-that is,- it willallow the table to swing outjust far enough for use and no farther.

I claim 1. In an edgc-burnishing machine, the con1- bination of the main shaft 0, having'upon it wrist-pins, the links H O, levers H O, and adjustable clamping-hubs G H with the rocking shaft D and hollow rocking shaft H", all operating together substantially as described, and for the purpose set forth.

2. In an cdge burnishing machine, the combination of the rocking shaft D, the arm D,and journalpieee and toolholder D D with the segment-piece E and lever E, all operating together substantially as described, and for the purpose set forth.

3. In an edge-setting machine, the combination of the bolt 13, sliding bar B", and hub B with the adjustable rod 13, swinging arm B", and table 13, all substantially as described,and for the purpose set forth.

ROBERT ASHE.
